HYDRANT.

SPECIFICATION forming part of Letters Patent No. 785,269, dated March21, 1905. Application filed February 17, 1904. $erial No. 193,967.

To all whom it may concern:

Be it known that I, ROBERT L. PoLLooK, a citizen of the United States,residing at Sterling, in the county of Rice and State of Kansas, haveinvented certain new and useful Improvements in Hydrants; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to hydrants; and it consists in the novelconstruction. and combination of the parts hereinafter fully describedand claimed. I

In the drawings, Figure l is a vertical section through a hydrantconstructed according to thisinvention. Fig. 2 is a detail side view ofthe cap at the bottom of the hydrant. Fig. 3 is a sectional plan "iewtaken on the linear a: in Fig. 1. Fig. 4 is a side view of one of thecatches. Fig. 5 is a detail side view showing a catch a engaging withthe projection j.

A is a ground-plate which is secured at the ground-level and providedwith a projecting boss ton its underside.

C is aplug-valve casing arranged below the ground-plate, and B is atubular distancepiece secured to the said plug-valve casing and t0 thesaid boss of the ground-plate and coupling the said parts rigidlytogether.

D is the plug-valve, which is journaled in the said plug-valve casingand provided with an angle-shaped water-passage d.

E is the inlet-passage of the plug-valve casing, which communicates withthe passage (Z when the plug-valve is placed in the open position. Adrain-hole e is provided in the dug-valve, which communicates with adrainhole 6 in the casing'when the plug-valve is in the closed position,so that the water is drained out of the delivery-pipe.

F is the delivery-pipe, which is secured to the upper end of theplug-valve and which passes upward through the said tubulardistance-piece and ground-plate and is provided with a delivery spout orbend f at its upper end and also a suitable operating-handle F.

The plug-valve D has a screw-threaded stem G at its lower end whichprojects through a hole in the plug-valve casing and is provided with anut g and a washer g, which is preferably a spring-washer of anyapproved make.

The plug-valve casing has a cylindrical projecting portion C at itslower end which is smaller in diameter than the main portion of thecasing, so that a shoulder h is formed, and H represents two lugs whichproject from the said portion 0, one on each side thereof.

I is a cap which is slipped over the portion C, so as to protect thenut. This cap is provided with angle-shaped grooves din its sides, thelower portions '11 of which are inclined, so that when the said groovesare slipped over the said lugs and the cap is partially revolved bymeans'ot' the projection I on its side the top edge of the cap is drawntightly against the said shoulder it. i

J isan adjustable hearing, which is screwed into the top end of theground-plate A and provided with a projection j for revolving it. Thedelivery-pipe F is journaled loosely in this bearing.

K is a collar secured on the delivery-pipe F below the bearing J andprovided with a ball-race la in its upper side.

K represents antifriction-balls, which run in the said race, and k is awasherplate which rests on the said balls. A washer-plate m is alsoarranged on the delivery-pipe in contact with the bottom end of thebearing J, and m is a spiral spring interposed between the twowasher-plates k and m. The spring at presses the plug-valve into workingcontact with the tapered socketot' the plug-valve casing, and thepressure of the said spring is adjustedby meansof the bearing J N is acollar secured upon the pipe F above the bearing J and 71 represents twosimilar catches which are pivoted on pins 01 which project from the saidcollar. These catches are formed right and left and they rest on lugs 0,which project at the bottom edge of the collar. These catches havenotches for engaging with the projection j of the adjustable bearing,and they have beveled portions 0', which enable them to engageautomatically with the said projection. These catches are curved so asto fit neatly around the collar, and they operate to lock the hydrant inthe opened and closed positions, respectively, of the plugvalve. Thesecatches can be turned over backward when not required in use.

The hydrant is shown in the drawings with the plug-valve in its openedposition, and the hydrant is turned around one-quarterof a revolution ineither direction in order to close the said plug-valve and stop the Howof water through the delivery-spout.

What I claim is In a hydrant, the combination. with a groundplate, avalve-casing, and a tubular distancepiece connecting the said casing andplate; of a valve in the said casing, a revoluble deliverypipe securedto the said valve and having a delivery-spout at its upper end, averticallymovable bearing J in which the middle part ROBERT L.
